It’s understood that the concept of the ‘secret menu’ kicked off after an interview with a McDonald’s manager in Scotland in 2015.

Back in 2015, a McDonald's manager in Scotland told Eater about the existence of a secret menu.

While he acknowledged that you can add, remove or change ingredients by special request, the ‘secret menu’ was “just a random person's guide to burgers you could potentially 'hack' at our stores.”

“If you are willing to pay for all the ingredients it is just another ‘grill order’ that we can make up.”
